Inventor: SCREPEL LOUIS
Filed: 1901-11-28
Granted: 1902-08-21
Abstract: 24,209. ScrÚpel, L. Nov. 28. Looms, pile forming and cutting in; stopmotions; starting - mechanism.-Relates to looms for weaving pile fabrics, such as velvets, carpets, plushes, astrachans, and similar fabrics. The pile wires a<2> employed are preferably formed of two steel strips united at the ends, slots m<2> or p' being cut in each strip, in a suitable position, to allow the knife E<4> to pass from one pile wire to the next adjacent one. During the cutting operations, the knife is gently pressed against the wire, with which it happens to be in contact, until the knife passes through the slot m<2> and enters between the steel strips ; then, after cutting the pile, the knife returns and passes through the slot p<2> into contact with the next pile wire. The knife E<4> is attached to a carriage C<3>, which slides upon a bar E<1>, suspended by means of stirrups E<3> and rollers G<4> from supports H<2>, secured to the breast beam K'. A catch G is mounted on the carriage C<3>, and engages with a projection 14 on a carriage D<4>, which travels along a fixed bar F<1> and is connected to a driving-chain N by means of a plate E<6> and rods 16, 17. A spring r<2> may be employed for pressing the knife against the pile wires. The catch G is lifted so as to miss the projection 14 when the pile is not required to be cut, and depressed when the pile is to be cut, by means of an arm m<1>, the motions of which are controlled by means of the draught and tie-up mechanism. Motion is transmitted to the chain N, from the loom shaft, by means of chain and toothed gearing, the speed ratio of which requires to be altered to suit the number of picks of weft between each insertion of pile wires. When the required number of weft picks has been shot, the loom is automatically stopped, and the weaver inserts a wire by hand. The stoppage of the loom is effected by means of a fast and loose pulley, the belt being shifted by an arrangement of levers actuated by an eccentric ; a band brake effects an instantaneous stoppage of the loom. After the pile wire has been inserted, the weaver starts the loom by moving a longitudinally-movable bar connected to a swinging- rod suspended from one end of a lever which actuates a starting-handle. The swinging-rod is - provided with a catch which engages with an oscillating lever actuated by means of a link and slotted bar secured to the loose pulley.
